Improvement in earth closets

w IMPROVEMENT IN EARTH CLOSETS.

The Schedule referred to in these Letters Patent and making part of the same.

To all persons lto whom-these presents may come Y earth commodes or cabinets, the plane of' section being from the front to the rear of the article;

Figure 2 is a transverse sect-ion ol' it;

Figure 3 is a top view; and

Figure 4, a front elevation of the damper, to be hercinafter described.

Figure 5 is a rear view of the eduction port, B, of' the hopper.

My improved earth closet or commode has the main characteristics or elements of others in use. In other words, it has a hopper to contain the dry earth used for covering and deodorizing the urinal and fecal matters deposited from time to time inthe receiving-bod. It also has a. dumper or devices for removing from such hopper, or receiving from it, as may be necessary, a charge of the'earth and depositing such in the excremeut-hod or receptacle.

In my endeavors to improve the earth closet or com. mode, I have sought to render it simple in construction and durable and etlicient iu operation, to impart to it a practical form and character, such as it has not heretofore had, and which, coupled with economy oi' cost, ywould. recommend it for general adoption, in all of whiclrl believe I have been, as l' have reason to believe, eminently successful.

In the said drawings- Adenotes the hopper, B its cdnct, C the dumpcr or measuring-box, D the discharging spout4 thereof, ll the seat, and E the lid or cover ot' such seat.

The bod-chamber or recel vin g-space beneni h the scat is represented at G.

The-damper C is constructed with an inclined top, a, and is open at bottom. It is supported on inc-lined ways or rails, b b, so arranged as to cause it, while being slid backward, to risc upward. Ilhe said dumper also has its top curved transversely, in manner as represented, there being through such top a passage, c.

-The dnmper is connectedwith the seat-cover F by means of connection-rods or devices, shown at H, by which, while the cover is being raised or turned upward on its hinges h, the. dumper shall he moved backward on its supporting-rails, and at the same time be allowed to rise upward on them, in conihrmity'wiih the slope ofthe bottom of the educt of the hopper.

Each ofthe connections H, as shown in the drawvwhile the dumper is in an advanced position.

ings, consists of a tubular rod, 1l, and a beutrod, fr,

the lat-ter being arranged to slide endwise or telescopically into the said tube.

lhe part -u is hinged at its lower end to the' seatcover, the part t being attached to the dumper. The dnmper will not move backward until the end of the part t' may roach the bottom of the bore of' the part u.

'From the above, it will be observed that the c0nstruction of each connection H admits ot' the cover being moved some distance without effecting any movement oi' the dumper. The connection H, however, may be a single rod or pit-man, jointed at its'ends to the cover and the dumper. 1n some cases the single rod is preferable to the compound pitmau or combination ofthe curved and tubular rods u t', as described,

but either maybe used, as circumstances may require.

lhe educt ol' the hopper has its bottom curved transversely, and inclined to iii',l to the top of the dumper, and there is a lip, d, raised on the said top, and arranged thereon in manner as exhibited inthe drawings. There is a hole or imluction-passage, c, in the top ofthe dumpcr.

The lip il is to prevent the escape or waste ot? earth over the top and down the front surface ot the dum per, while it may be cit-her at rest or in motion'.

A spout, I), is hinged to the dumper at its rear, and serves not only as a means of closing the discharging opening of the dumper, preparatory tothe admission oi' a charge into the dumper, but, 0u an advance of the dumpen', to direct, upon a deposit of excl-ement in the bod, the earth that may be discharged from the dumper.

A wheel or roller, I, arranged beneath tbe spout or with respect to itin manner as represented, and supported by a shaft, K', so as to be capable of freely revolving, serves to eli'ect the upward movement or closing ofthe spout during a retreat or falling back of the dumpcr. ln. thc'place of the roller I sometimes employ a stationary bar or stud, but the roller will operate with less friction and noise, and therefore is preferable. I terln such bar or roller the spout-closer.

While raising the lid or cover ot' the seat the dumper will be forced baclnvard, its spout Dwill be closed, and the hole in the top ot' the dumper will be carried underneath that in the bott-om of the hopper educt. As a consequence, when there may be dry earth in the educt, such earth, or a portion oi' it sul'licient to charge the dumper, will fall into it. While next depressing the lid or cover ofthe seat, the dumper will be drawn forward, and the partp, in rear of the hole in its top, will he brought directly underneath the opening in the bottom oi the educt, and will close such opening so as to prevent the escape of earth ii'om the educt, During the, advance of the dumpcr the spout will fall 'into a more inc-lined position, so as to open the lower part of the ,dumpertaud allow ,the charge of earth to escape charge of earth in case it should become so compactedl as to remain in the ednct when the latter may be open to the dumper.

From the above it will be seen that the dumper has VVits top aswell as its bottom inclined to the horizon;

also, that dui-ingr,r a retreat of the dumper it has an upward movement; also, that during an advance it has a downward movement. 1t will further be seen that the bottom ot' the eductof the hopper isalsoinclined, as is the top of the dumper; also, that both the top of the damper and the bottom ot the ednet of the hopper are curved or concave transversely, all otI which is t'or the purpose of facilitating, thronjh the action oi" gravity, the discharge. of the earth from the educt oi the hopper, and also i'rom the dumper.

I am aware. of the earth closets described in the United States patents Nos. 90,688, 90,709, 91,474, and 91,855, and, consequently, malte no claim to leither of them, or any part or combination or arrangement of devices described or represented in the speciiication or drawings of either ot' such patents.

What I claim as my invention maybe stated as foilows; that is to say- The combination and the arrangement of the agitator K, with the cduct B and the damper O combined therewith.

Also, the hopper, as made with the inclined bottom, and the damper as made, with the correspondingly inclined top, and supported by inclined ways, so as to be capable ot' beineV moved, in manner as set forth, with reibrcnee to the hopper.

Also, the arrangement of the rods or devices H, by which the domper is connected to the seat-cover F so as to be movable thereby, as set forth, such devices,

by the said arrangement, beinedisposed entirely aboveV the hinges ofthe cover.

Also, the dumper 0,115 made, with the concave'and inclined top and the hopper ednct, as constructed with the inclined and curved bottom, as described, to operatc with such top ofthe dumper.

Also', thc arrangement and combination ofthe lip l with the dmnper (i and eductl of the hopper A, as described.

Also, the spontl) and its closer l, as arranged `and combined with the dumpcr C, substantially in manner and so to enable the spout to operate as set forth.
